Abstract
Web caching plays a key role in improving the performance of the web by reducing the latency of delivering web objects to the users. On the other hand, a simulation tool plays a key role in studying the behavior of any network such as studying the effects of web caching on the performance of the network. The aim of this work is to present a tool for simulating a web proxy caching for windows operating systems since there is no existing well-compatible simulation tool for windows operating systems that can simulate Hit Ratio (HR) and Byte Hit Ratio (BHR) for traditional caching policies. The proposed simulation tool is called Windows Web Proxy Caching Simulation (WWPCS). The results show the performance of traditional web caching policies for different cache’s sizes. Moreover, in order to show the efficiency of WWPCS, the results of running WWPCS are compared to the results of running a Unix-based tool.
Highlights
Web caching improves the web performance by storing web objects close to the clients, which reduces the latency of delivering web objects to the end-user
The aim of this study is to introduce a web proxy cache simulation tool called Windows Web Proxy Caching Simulation (WWPCS) which can be used in performance analysis of different web caching policies
A simulation tool is defined as a piece of software or hardware which can predict the behavior of a certain model that represents the characteristics of a system
Summary
Web caching improves the web performance by storing web objects close to the clients, which reduces the latency of delivering web objects to the end-user. It utilizes the bandwidth of the network which is considered as an important aim for network administrators. It reduces the loads on the origin servers (Jelenković and Radovanovic, 2009). In (Markatchev and Williamson, 2002) it has been recommended developing a caching simulation tool for windows operating systems
